That is a good question. I think it depends on the person but I found them whenever I cut out anything with gluten, I had A LOT less aches and pains. I have heard some people find that chocolate and dairy cause flair ups. For me gluten seems to be a trigger. That said, I live with others who I have to cook for so I have a hard time going gluten free apart from a few months at a time. When it gets really bad, back I go on gluten free.

Hope this helps!

I think different people have differing experiences. Food makes little to no difference for me, but rest and exercise do. If I am too inactive, the pain flares (or maybe I just notice it more.) And if I get overtired, pushing myself hours after I should quit, I get a flare.
